YARN CLEANER.

Original application filed June 8, 1822, Serial No. 566,721.

To all whom it may concern:

Be it knownthat I, Harm. E. VAN Nnss, a citizen of the United States, residing at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Yarn Cleaners, fully described and represented in the following specification and the accompanying drawing, forming a part of the same.

This invention relates to yarn cleaners for eliminating impurities, such as parts of seeds, parts of stems, slubs, specks and other particles from yarn before the yarn is woven into cloth, so that a superior quality of cloth may be produced from comparatively inexpensive yarns.

A simple and effective device for this purpose is described and claimed in my copending application filed June 8, 1922, Se-..

rial No. 566,? 21, of which the present application is a division. The yarn cleaner described in the said original application provides means forming a slot located at one side of the yarn and arranged to engage particles projecting from the yarn and to guide such particles away from the yarn. The present invention consists in providing such a slot between two acute edges and in certain features of construction and arrange ment hereinafter particularly described and claimed.

In order that the invention may be clearly understood, I will describe in detail a yarn cleaner embodying the invention which is illustrated in the annexed drawings, in which Fig. 1 is a side elevation of the yarn cleaner; and

Figs. 2, 3, 4L, and 6 are enlarged views of a cleaning unit of the yarn cleaner shown in Fig. 1, Fig. 2 being a side elevation, Fig. 3 a front elevation showing the bar sectioned on the line 8-3 of Fig. 2, Fig. l a transverse section on the line 4l4.- of Fig. 2, Fig. 5 a side view with two of the cleaning members removed, and Fig. 6 a plan view.

The yarn cleaner illustrated in the drawings comprises a bar 10, on one end of which is mounted a tension device 13 of ordinary construction. In alined relation along one side of the bar are mounted the cleaning units 15. As the units are all alike, a description of one of them will suffice.

A cleaning unit 15 comprises two upper cleaning members 20, and two lower one side'oi' the yarn.

Divided and this application filed February Serial No. 691,569.

cleaning members 30, 80. The cleaning me1nber 20 comprises a supporting portion or foot 21, an outwardly bent portion 22, an outwardly flaring ear 23, and a cleaning blade 2-1. The cleaning member 20 is similar to the member 20 and its parts are identified in the drawings by the same reference numbers as the parts of the member 20, a prime being added to each number. The lower cleaning member comprises a supporting portion or foot 31 and a blade 34, while the lower cleaning member 30 has a similar foot 31 and a similar blade 3%.

The tour cleaning members are secured to the bar 10 by screws 16 passing through their feet. A removable spacing member 17 is placed between the feet 31, 31 of the members 30, so.

The upper blades 24:, 241 are bevelled on the outside at 25, 25 to form acute cleaning edges 26, 26. These cleaning edges are curved as indicated in Figs. 1, 2 and 5. The lower blades 34, 34 are bevelled on the outside at 35, 35 so as to form acute cleaning edges 86, 36 which are curved somewhat more sharply than the cleaning edges 26, 26. The cleaning edges 26 and 36 lie in a common plane, and the cleaning edges 26 and 36 lie in a commonplane. These planes are parallel and separated by a distance determined by the thickness of the spacing member 17. The distance between the planes should be substantiz'illy equal to the diameter of the yarn, so that the planes are tangential to the yarn at opposite sides thereof. In order to adjust the units for use in connection with yarns of different diameters, a plurality of spacing members of diflferent thiclrncses may be provided.

The cleaning edge 26 is cut away at 27 and the front corner 28 of the cleaning edge 26 is turned in. Similarly the clean ing edge 36 is cut away at 37 and the front corner 38 of the cleaning edge 36 is turned in.

The edges 26 and 36 form between them an opening or slot 40 which lies wholly at The slot 40 tapers inwardly from its entrance end d1 to a neclr 42 of less width than the diameter of the arn, and tapers outwardly from the neck 42 to its discharge end 43. The entranceend d1 of the slot i0 is immediately adjacent to the yarn A, while the discharge end 43 of the slot is some distance below the line of travel of the yarn. The opening or slot -10 included between the edges 26 and 36 is similar to the slot 40.

In the operation of the cleaning device describech the yarn is passed around the tension device 13 and then drawn downward and forward between the cars 23, 23 of each unit until it extends in a straight horizontal line, passing between the blades 2%. and 2st of each unit and between the turned-in corners 28, 38 ot the blades 26 and 36 of each unit. It is then drawn continuously :tor

ward. The particles adhering to the yarn and projecting therefrom enter the slots -10, 40. As the yarn is drawn forward, the particles pass along longitudinally in the slots 40, 40, being separated from the yarn at or about the time they reach the necks 4-2, as. The necks are, however, of such width that the particles being separated from the yarn and the particles which have been separated are moved continuously tor-ward through the necks and the outwardly tapering portions of the slots by the pressure of the particles behind them, which is caused by the pull of the yarn. The particles are, therefore; continuously discharged from the lower ends of the slots.

What I claim is: 1. In a yarn cleaner for removing particles adhering to a traveling yarn, a cleaning unit comprising members having opposed spaced acute edges forming the guiding slot at one side of the yarn, the entrance end of said slotbeing immediately adjacent to the yarn and the discharge end remote from the yarn, said slot tapering inwardly from its entrance end toa neck of less width than the diameter of the yarn and tapering outwardly from said neck toward its discharge end.

2. A yarn cleaner for removing particles adhering to a traveling yarn, comprising a blade having an acute edge, asecond blade having an acute edge spaced from the edge of the first blade and forming therewith a guiding slot extending in the general direction of the travel o1 theyarn but diverging from the line of travel so that its entrance end is in'n'i'iediately adjacent to the yarn and its discharge end is remote from the yarn, and tapering inwardly from its entranceend to a minimum width less than the diameter of the yarn but sutlicient to permit longitudinal travel of particles in the slot under the effect of the pull. of the yarn upon particles entering the slot, the portion oi? the slot whose width is less than the diameter or the yarn. being located wholly at one side of the yarn, and. means for retaining said blades in fixed relation to each other during the operation of the cleaner.

3. A yarn cleaner for removing particles adhering to a traveling yarn, comprising a pair oil parallel blades lying adjacent to opposite sides of the yarn and having acute operative edges inclined away from the line of travel of the yarn and a second pair of parallel blades having acute operative edges opposed to the edges of the first blades respectively and forming therewith slots tapering inwardly from their entrance ends.

n. A yarn cleaner for removing particles adhering to a traveling yarn. comprising a, pair of parallel blades lying adjacent to opposite sides of the yarn and having acute operative edges inclined away "from the line oi travel ol the yarn, and a second pair oi par allel blades having acute operative edges opposed to the edges of the iii-st blades 1e spectively and torming therewith slots taper ing inwardly from their entrance ends. the trout corner of one of the operative edges of each pair oi? blades being turned inwardly.

5. A yarn cleaner for removing particles adhering to a traveling yarn comprising an upper pair of parallel blades lying :nljaccnt t opposite sides of the yarn and having acute lower edges curving downwardly 'irom the line oi travel of the varn, and a lower pair o't parallel blades having acute curved edges opposed to the edges oi. the first blades respectively and forming therewith curvet slots tapering inwardl from their entrance ends.

6. It yarn cleaner for removing particles adhering to a traveling varn comprising an upper pair of parallel blades lying adjacent to opposite sides of the yarn and having acute lower edges curving down wardl from the line of travel of the yarn, and a lower pair of parallel blades having acute curved edges opposed to the edges of the iirst blades respectively and forming therewith curved slots tapering inwardly from their entrance ends, the lower front corner of one of the upper blades being turned inwardly so as to lie aojaccnt to the upper side of the yarn and the upper front corner of one of the lower blades being turned inwardly so as to lie adjacent to the lower side of the yarn.

In testimony whereof I have hereunto set my hand. I
